| 🇬🇧 | 🇬🇧 |
| What are the 2 types of mixtures? | Heterogeneous-2+ materials that are still visible/cloudy solution/homogeneous-2+ pure substances mix to look like 1 |
| What is archimedes' principle? | Any body completely or partially submerged in a fluid at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body. |
| What is buoyant force? | Particles pushing up on object |
| How do you classify matter | Matter is either pure substance or a mixture, mixture can be homogeneous/ solution or heterogeneous |
| What affects solubility? | Agitation, temperature, and surface area |
| What is compressibility? | Only gas can be compressed, not solids and liquids. gases must be in a sealed container, particles need to have enough space apart to act as a gas, and there needs to ba an external force applied to it |
| What affects viscosity? | Heat and clumps/thickness |
| What is buoyancy? | Tendency for materials to rise or float in a fluid |
| How do you calculate pressure? | Pressure=force/area p=f/a |
| What is density/average density? | Density-mass per unit of volume for a substance/ crowdedness of particles d=m/v average density-total mass of an object divided by its total volume |
| Solute vs solvent | Solvent- thing that does the dissolving solute- thing that gets dissolved |
| What are the properties of the states of matter | Solid-has fixed shape & volume liquid-takes shape of container & fixed volume gas-spreads out, not fixed |
| What are the 3 states of matter? | Solid, liquid, gas |
| What is the definition of flow rate and viscosity? | Viscosity-thickness of a fluid flow rate-amount of fluid that passes a point in a certain amount of time (speed) high viscosity=low flow rate |
| Methods of seperation | Mechanical, magnetism, flotation, settling, sifting, filtration, dehydration, distillation |
| What are the changes of states? | Fusion, solidification, evaporation, condensation, sublimation, deposition |
| What is neutral buoyancy? | The object has the same density as water so it stays suspended in the water |
| What is pneumatics? | Gases used to move objects with pressure |
| Particle model of matter | All matter is made up of tiny particles, there is space between the particles, particles are always moving at heat affects their movement, all particles in a pure substance are the same, pure particles are attracted to each other |
| What are hydraulics? | Liquids used to move objects with pressure |
| What are fluids? | Anything that flows, gas and liquids |
| Matter vs mass vs volume | Mass-something made up of particles volume-takes up space matter-anything w/ mass and volume |
| WHMIS acronym | Workplace Hazardous Materials Information System |
| WHMIS symbols | Biohazard, explosive, flammable, oxidizer, compressed gas, corrosive, poison, serious health hazard, less serious health hazard, may damage the environment |
